Can't you just run the forum in an XHTML template? Maybe I'm not sure of the nature of your problem. Where are these tags showing up? Are you importing the forum info to other parts of your site?

Does the page have an XHTML DOCTYPE?

Perhaps you only need to use HTML codes instead?

yes the doc type is XHTML. will it be a good idea to change my doc type to HTML4.0?

Which version? I'm assuming you are using phpbb2 because the stock templates in phpbb2 use <hr /> and <br /> with a HTML doctype, switching doctypes won't help because other code won't validate as XHTML. Not sure what the reasoning is, I vaguely remember reading something about it once.

If the DOCTYPE is XHTML, why are you receiving validation errors for valid XHTML tags? I'm confused.

When the DOCTYPE is XHTML it doesnt give me any validation errors but the XHTML tags are not working in my forums.like when I write <hr /> it doesn't draw any horizontal line but simply using <hr> works.

Which version of phpBB are you using?

I am using phpBB 2.0.22

After reading this several times I might be getting it to some degree. You're saying that if you use XHTML tags in forum posts they don't work? That makes some sense. It's kind of like the [bb] code many forum packages use. The forum's internal systems convert what you post into the final page.

Am I understanding the issue?

Well if what was suggested above is what you are getting at, using them in posts....

I did a test post on my test forum and using <hr> produces a line , usng <hr /> produces a line but the trailing slash is deleted by the forum. If you go to edit the post it has been removed. To change this behavior you would have to edit the php script, you might find something on the phpbb forums for doing this.

Whatever the case direct HTML input (even the limited HTML in phpbb2) is a security risk and should not be used for a public forum, it isn't even an option in phpbb3. Check the modifications forums on phpbb.com, they have BB code mods that will add the <hr> tag.

Yes Bill thats the issue
